How Good is a MERV 8 Air Filter?

MERV 8 air filters are 90% efficient in capturing particles between 3 and 10 microns in size. They are considered superior filtration compared to air filters with a lower MERV rating, and are applicable in homes and window air conditioning units. But is filtration enough? In many cases, a MERV 8 air filter is more than adequate, but if you're concerned about outdoor air pollution, family members with respiratory problems, or pets in the house, then opting for a higher MERV rating might be a good idea. To be classified as a MERV 8 filter by the NAFA (National Air Filtration Association), a filter must filter at least 70% of E3 particles (3.0-10.0 µm) and 20% of E2 particles (1.0-3.0 µm).

In addition to 70% of E3 particles, it also filters 30% of E2 particles and 1.9% of E1 particles (0.3-1.0 µm). However, it is not designed to trap the smallest particles that fall into the E1 category, such as pet dander. Essential was found to have a retention rate of 81.5%, meaning that 81.5% of the dust particles introduced into the filter were successfully filtered from the air. MERV 8 pleated filters are made of 100% synthetic media to capture common airborne contaminants between 3 and 10 microns in size, such as pollen, pet dander, lint, and dust mites. Before buying one, there are a few things you should know. While these filters trap pollen, dust, mold and other basic air pollutants very well, they're not ideal if you have allergies or pets.

In addition, if you live close to smoke pollution, we recommend that you choose a filter with a higher MERV rating. A MERV 8 air filter is common in homes, commercial buildings, paint booths and industrial workplaces. Upgrade your standard disposable filter to MERV 8 filters at an affordable price for efficient air purification in your home without affecting air flow. If you're new to selecting air filters and need help deciding which one is best for your needs, consider pleated filters that are MERV 8 to 13. These can effectively filter small particles and reduce the pressure drop. However, if you need to trap harmful viruses and bacteria, smoke or other forms of air pollution, then opt for an air filter with a higher MERV rating. Generally speaking, anything under a MERV 13 air filter should provide very efficient air purification in a home without affecting air flow. But if you simply need a filter to trap pollen, dust mites, and hair, then a MERV 8 filter should do the job. In addition to selecting the right type of filter for your needs, it's also important to follow the manufacturer's recommendations for maintenance and replacement.

This will ensure that your air purifier works properly and continues to provide clean air.
